Prepare view-engine for non-KFileItem usecase

Up to now the view-engine only provided a model-implementation that
supports file-items. The view-engine always had been designed to be able
to work with any kind of model, so now a KStandardItemModel is available.
The plan is to convert the places panel to the new view-engine. It should
be no problem to fix this until the feature freeze - in the worst case
the places-panel code could be reverted while still keeping the
KStandardItemModel changes.
